Solution Overview

Problem

Existing DSL communication systems face challenges in providing high-speed data services to multiple dwelling units due to the degradation of DSL modem performance caused by bridged taps and the impracticality of additional wiring, especially in complex installations like apartment buildings, where traditional splitter configurations are inadequate for VDSL services.

Innovation Solution

The introduction of splitter wall plates that separate DSL and POTS signals using a splitter and switch configuration, allowing for the simultaneous provisioning of DSL, POTS, and VoIP services without additional wiring, by routing signals through a 'home run' configuration that avoids bridged taps and supports VoIP distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If microfilters are installed at each telephone jack to separate DSL and POTS signals, then DSL signal interference from telephones is reduced, but bridged taps are created that significantly degrade DSL modem performance

Engineering Contradiction:
ImproveDSL signal interferenceVSAvoidDSL modem performance
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The system segments the signal separation function by placing a central splitter at the network interface device rather than using distributed microfilters at each telephone jack. This consolidation eliminates the creation of multiple bridged taps while maintaining signal separation functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A dedicated splitter device acts as an intermediary component at the network interface device to separate DSL and POTS signals. This intermediary prevents direct connection between DSL and POTS equipment, eliminating the harmful interaction that creates bridged taps.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a splitter is installed in the network interface device with separate wiring to the DSL modem, then DSL and POTS signals are properly separated, but additional wiring becomes impractical for multi-dwelling units

Engineering Contradiction:
Improvesignal separationVSAvoidwiring complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The splitter wall plate is designed to serve multiple functions: it provides signal separation, maintains existing wiring configurations, and supports both DSL and POTS services simultaneously. This multi-functionality eliminates the need for separate dedicated wiring while achieving proper signal separation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the splitter functionality directly into the existing wall plate structure, combining multiple functions (signal separation, wiring termination, and service distribution) into a single integrated component. This eliminates the need for additional separate wiring infrastructure.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If traditional splitter configurations are used in multi-dwelling units, then DSL services can be provided, but DSL connection speeds are degraded due to bridged taps from telephone wiring

Engineering Contradiction:
ImproveDSL service provisioningVSAvoidDSL connection speed
Core Design Contradiction:
ProductivityVSSpeed

Solution Approach 1:

The harmful bridged tap connections are extracted from the system by reconfiguring the wiring topology. The splitter wall plate creates a clean separation point that prevents telephone wiring from creating indirect paths back to the DSL signal, thereby extracting the source of speed degradation.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If additional wiring is installed to avoid bridged taps, then DSL performance is improved, but installation becomes impractical in existing multi-dwelling units

Engineering Contradiction:
ImproveDSL modem performanceVSAvoidinstallation feasibility
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The splitter wall plate provides a dynamic configuration capability through switches that allow flexible routing of POTS and VoIP signals. This adaptability enables proper signal separation and performance optimization without requiring fixed additional wiring installations, making it feasible for existing buildings.

Inventive Principle:
Principle #15Dynamics
